Mechanical Explanation for the Hemodynamic Efficacy of Right Atrial Appendage Autografts Used in Neo–Semilunar Valve Leaflet Reconstruction
Atrial appendage tissue's greater distensibility may allow greater leaflet coaptation and accommodate expansion over time, enhancing growth potential. However, the greater pliability may predispose to valve prolapse if too much tissue is used or in the setting of elevated diastolic pressures. Longitudinal studies are warranted to further explore the potential of atrial tissue for valve reconstructions.
